Natural Bridge sandstone arch

In Powell and Wolfe counties, a 78-foot-long, 65-foot-high arch of Corbin Sandstone (Breathitt Formation, Middle Pennsylvanian) spans a gorge on the Middle Fork of the Red River.

Quartz-rich river sands capped softer Mississippian limestones; Alleghenian uplift and millions of years of freeze–thaw and stream cutting carved the arch. Long a landmark for Indigenous hunters and settlers, the site became a railroad excursion stop in the 1890s and one of Kentucky's original state parks in 1926, beside Red River Gorge and the Daniel Boone National Forest.
